Let's divide 83754412 by 445
The aim is to understand the frequency of 445 in 83754412.

Going ahead to step 1:
If we divide 8 by 445, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 445

Going ahead to step 2:
445 can be fit into 83 0 times, resulting in a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 83, we end up with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 445

Moving on to step 3:
837 divided by 445 is 1 with a remainder of 392.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 392 after subtracting 445 from 837.
Append the next digit (5) from the dividend to 392 and continue with: 3925 / 445

Let's proceed to step 4:
If we divide 3925 by 445, we get 8 and a remainder of 365.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3560 from 3925 to get 365.
Grab the next digit (4) from the dividend, add it to 365, then carry on: 3654 / 445

Step 5:
If we divide 3654 by 445, we get 8 and a remainder of 94.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtract 3560 from 3654 to get 94.
Bring next digit (4) of the dividend behind the 94 and repeat the process: 944 / 445

Going ahead to step 6:
When dividing 944 by 445, we get 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 1882.0
Subtract 890 from 944 to get 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 445

Advancing to step 7:
If we divide 541 by 445, we get 1 and a remainder of 96.
Put 1 as the next digit of the answer. 
Result so far: 18821.0
Subtract 445 from 541 to get 96.
Grab the next digit (2) from the dividend, add it to 96, then carry on: 962 / 445

Advancing to step 8:
The number 445 fits into 962 2 times, leaving a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 188212.0
Subtracting 890 from 962 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
445 goes into 720 1 times with a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 188212.1
Subtract 445 from 720 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 10:
If we divide 2750 by 445, we get 6 and a remainder of 80.
The next digit of our result is 6. 
Result so far: 188212.16
If we subtract 2670 from 2750, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
The number 445 fits into 800 1 times, leaving a remainder of 355.
The number 1 becomes the next digit in our result. 
Result so far: 188212.161
Subtracting 445 from 800 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 12:
The number 445 fits into 3550 7 times, leaving a remainder of 435.
Record the quotient 7 as the next digit in the result. 
Result so far: 188212.1617
If we subtract 3115 from 3550, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

On to step 13:
The number 445 fits into 4350 9 times, leaving a remainder of 345.
Put 9 as the next digit of the answer. 
Result so far: 188212.16179
Subtract 4005 from 4350 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 14:
445 goes into 3450 7 times with a remainder of 335.
Record the quotient 7 as the next digit in the result. 
Result so far: 188212.161797
Subtracting 3115 from 3450 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 15:
If we divide 3350 by 445, we get 7 and a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 188212.1617977
Deduct 3115 from 3350 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final outcome is 188212.1617977, with a leftover of 2.35e-06.
